Abstract
Disclosed are transparent, clear cosmetic stick compositions of the type gelled with soaps such as sodium salts of saturated fatty acids, and containing an alcohol (e.g., propylene glycol) and water. The compositions include sodium salts of methyl carboxy derivatives of ethoxylated lauryl alcohol (e.g., sodium laureth-13 carboxylate) to improve transparency and clarity of the stick compositions. The soap gelling agent can be a mixture of sodium salts of fatty acids (e.g., saturated fatty acids) of carbon chain length C.sub.12 -C.sub.22. The stick compositions can include deodorant active materials (such as fragrances, bacteriostats, bacteriocides, etc.) so as to provide transparent, clear deodorant stick compositions for application to axillary regions.
